You have several options for finding your restore points, but first you have to ensure that System Restore is functioning properly.

1.) Press the Windows Key + R ( Run command ) and type in : services.msc
2.) Make sure that the service called Volume Shadow Copy is switched to Automatic, and then press OK

3.) Right click "This PC", or "Computer", or "My computer", however it's named. Then click "Advanced System Settings", and look for a tab called System Protection

Then you should see your partitions listed there, and Protection can say Yes or No. I have disabled System Protection, so you will not see it. But if you look above, at the answer that has been provided by AAA1992 you will see that he has there all of his partitions being listed.

3.1.)If you want to backup your WINDOWS system ( System Restore, right? Crucial System Files, etc. ) then you will simply select the C: drive, click COnfigure, and see how much you want to allocate for your backup. The more you allocate, the larger the amount of files that Windows will save for later on, in case you are in trouble.

If there is no existing Restore Point you can simply use the Create button(In my case it is grayed out, I have totally disabled this feature on my computer - I don't use it ).

After you have chosen the size of the System Restore Point in step 3.1.) above, then you can just click Create, and Voila! You have a restore point that you can use later on when in trouble.

4.) How can you restore?

Many ways:

4.1.) You can either restore from this menu above, by clicking System Restore ( greyed out in my case, top of the window ), or if you have trouble booting up you can simply press shift F8 and the boot menu will appear.

Just go to conntrol panel, type restore in the search field on the top right corner. You will see a list of options, select 'Backup and Restore'. then continue to select 'another backup to restore fiiles from'. That is where youcan see restore points.
